Best way to create a many to many page

I’m flying now with Wappler creating full CRUD pages very quickly.

I have three tables - schools, events and a many-to-many to link them. This is because multiple schools can be linked to an event and multiple events can be linked to a school.

What’s the best way to build this page to make it easiest for admins to manage it? I’m thinking they select the event, then see a list of all the schools and tick all those which are to be linked to it. I’m struggling to work out in my mind how to go about that, though.

Can someone give me a steer? Cheers.
